Just a short while ago, the various Forces didn’t know that the others existed, and now they’re calling each other “sis” and “bro”. I’m surprised that they didn’t start calling Iris and Barry “mom” and “dad”. Not that they should. As Nora/XS will attest, Iris and Barry aren’t really the greatest of parents.
Cisco was supposed to make a life-altering decision, but I don’t think he made any kind of decision this episode. Joe on the other hand quit the force! Now who’s going the keep Lt. Asshole in check?
